I'm not sure about this.

On one hand a cheeseburger should definitely involve a burger patty, cheese and some kind of roll. But the roll, cheese and other fillings could all vary considerably and yet the thing would still reasonably be described as a cheese burger.

I would say that a caeser salad might be made with lettuce other than Romaine and requires grated parmesan in addition to the dressing and croutons. That said, I would agree that the object described above is not a caeser salad - I don't know where the line is, but that is way over it.

In general I think you have to be a bit wary of regional/national differences. If you tell a German and a Brit that something comes with potato salad they will not have the same substance in mind.

And i've never even heard of French dip. However the wikipedia entry for it does suggest there is some variation in how it is served. Sounds good anyway
